  • Weldable, low lead and lead-free plumbing fittings and methods of making the same
    Patent number: 10760693
    Abstract: A plumbing fitting that includes: a fitting body having a plurality of ends; and a cover element joined to the body with a weld in proximity to and spaced from an interface in contact with a potable or non-potable aqueous medium. The body and the cover element are fabricated from a lead-free or low lead, copper or copper-silicon alloy having a thermal conductivity of ?45 W/(m*K). Further, the weld has a centerline that is ?6.4 mm from the interface and/or a heat affected zone that has an average width ?400 ?m and is spaced from the interface. The plumbing fittings include but are not limited to ball valves, gate valves, elbows, check valves and other fittings without stems.
    Type: Grant
